The ordering of our solar system is considered to be VERY rare and it plays a big part as to why life was able to form on our planet. I believe most star systems have what is called a ‘Hot Jupiter’ that orbits close to its host star which prevents rocky planets from forming (it essentially steals all of the materials in the area during the stars formation and even if a rocky planet forms, the hot Jupiters gravity usually ends up ejecting it from the system entirely).
We actually haven’t found a single star system similar to ours where all of the rocky planets orbit close to the star and the gas giants orbit further away.
